Yes after 2 weeks defrosting on a tropical paradise your new handle is now "Melt" Welcome back. You will find that the forum discussions (arguments) are hotter than the tropics
22) Message boards : Number crunching : Questions For Travis (Message 15782) Posted 17 Mar 2009 by Copycat-Digital for WCG* Post: It can handle quite a bit but C is probably stressing it the most currently because the workunits complete so quickly. When you increased the length of the work units there was remarkable improvement in the response. It would appear that the number of shorter work units (S7x and S8x) generated lately increased. This put the stress back on the server as well the traffic on the network. Wouldnâ€™t another increase in length of the work units help?

I want to got to 850Mhz and beyond! :P I could only afford a 4830 I installed yesterday Upped the clock to 615 MHz and guess what -- My 1st sub 1sec wu !!!!! http://milkyway.cs.rpi.edu/milkyway/workunit.php?wuid=23350847
24) Message boards : Number crunching : new workunit queue size (6) (Message 13301) Posted 28 Feb 2009 by Copycat-Digital for WCG* Post: [/quote] Bang! Travis has recently repeated that there are plenty of WUs on the server side. The problem is releasing them to the clients (us), which I understand requires a server memory fix which will be done on Monday, hopefully, the 20/6 WUs being a temporary fix. It has nothing to do do with WU shortage so blaming ATI will do nothing for you. Go here; http://milkyway.cs.rpi.edu/milkyway/server_status.php There are 700 WUs for you not being gobbled by ATIs [edit] it just went up to 800 +[/quote] Sorry I think you missed Server status shows 753 ready I immediately hit update on my dry quad and received 0 Iâ€™m not blaming ATI (its ability is amazing!) but this started to escalate when more and more crunchers uses their ATIâ€™s. I looked randomly at 10 of the top 100 computerâ€™s RAC â€“ they are all ATI equipped. Other fast PCâ€™s may also contribute to this. Iâ€™m also guilty because I OCâ€™d my Q8200 to 2.9 GHz to pump up my RAC Itâ€™s doing a S82 in 250 seconds Yesterday I turned down the cache to minimum 0.01 but its scheduler still wants 9000 seconds of work and repeatedly ask for more every 60 seconds even with 76 wuâ€™s ready to start Doesnâ€™t this put a big strain on the network and server? Edit I can also install ATI but with my luck my RAC will go down

The baby ATI cruncher grew into a monster with an unsatisfying appetite A quick calculation shows that a 4850 in a quad can gobble up +/- 1400 work units in an hour! These monsters multiplied rapidly when a lot of crunchers rushed to the stores to get theirs Now the server and network canâ€™t keep up feeding these hungry monsters. Result: Everyone is starving!
26) Message boards : Number crunching : GPU crunching question please (Message 13041) Posted 27 Feb 2009 by Copycat-Digital for WCG* Post: 1) Any news on the Nvidia app? 2) Will it work on the 9x series? Yeah the only current GPU app for milkyway is Cluster Physik's which uses ATI cards. We're working on one for Nvidia. [quote]As soon the Nvidia is ready I'm up for testing it on my 9600M GT. If the project does not drop the double precision requirements, it will also require very recent nvidia cards (CUDA compute capabilities 1.3 required, your 9600GT supports 1.1). That means only the GTX 200 line will work. That is the same the reason the ATI GPU app is only available for HD3800 and HD4800 cards.
27) Message boards : Number crunching : should be a bunch of work available (Message 10123) Posted 8 Feb 2009 by Copycat-Digital for WCG* Post: Thanks Trevor & everybody involved for sacrificing your Sunday !!!!
28) Message boards : Number crunching : Jan 24 credit change complaints/comments here (Message 9058) Posted 25 Jan 2009 by Copycat-Digital for WCG* Post: I had the same problem in my shop. A few people paid me with counterfeit money. I stead of implementing a way to stop this I doubled my prices. I did not listen to my honest customers complaints now I lost them all!
